SPECIFICATION forming part of Letters Patent No. 265,956, dated October 17, 1882.

Application tiled J' une 12, 1852.

To all whom it may concern Be it known that I, JAMES M. GARDNER, of Ramsey, in the county of Fayette and State of lllinois, have invented certain new and useful Improvements in Steam-Plow Running-Gear; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of' this specification.

This invention relates to steam plowing apparatus; and it consists in certain improvements in the construction and operation of the same.

In the drawings, Figure 1 is a top view; Fig. 2, a bottom view; Fig. 3, a vertical longitudinal sectional view on the line :v x, Fig. 2; and Fig. 4 is a detail sectional view.

Referring by letter to the drawings, A designates the platform of the machine., which is mounted on a rotary main axle, B, `journaled in brackets O C on the under side of the platform, and carryingdrive-wheels D D, each having a hub or tiange, E, projecting inside, which is provided with notches F F. The notches F F are adapted to be engaged by corresponding lugs, G G, on sliding collars H H', arranged on the square portions I I of axle B. The latter collar, H', is provided with a circumferential groove, J, engaged by the bifnrcated end K of a lever, L, pivoted by a pin or bolt, M, to the under side of platform A, its movement being limited by a bracket, N. A flat spring, O, is arranged to bear on lever L to force the collar H'into engagement with the tlange on the wheel; but by operating said lever the collar is thrown out ot' engagement, and the axle B revolves with only the other wheel, thus causing the machine to turn around very short.

To actuate lever L, a lever, P, is secured to its powerend, which lever P extends up through an opening, Q, in platform A, and is pivoted in a bracket, li, thereon, its top end being ar ranged in a rack, S, as shown.

To facilitate turning and to guide the machine, a bracket, T, has its shank U passed up (No model.)

| through a central opening, V, in the licor at the front, and provided with an operating-rod, W. The bracket Tcarries a roller, X, having a circumferential rib or flange, Y, to prevent slipping.

Z Z are suitable water or fuel boxes, between which the steam-boiler is adapted to be secured.

A' designates a desired number of rearwardly-extending beams or pieces, which are hinged or pivoted at their front ends, B', to platform A, and connected at their outer ends bya transverse strip, C', to which is pivoted' by a link, D', a lifting-lever, E', having its fulcrum on a standard, F', and its power end adapted to engage a rack or serrated standard, G', on the platform. To the rear ends, I', ot' pieces A' are hinged or pivoted independently the beams J', carrying plows K'. Thus the plows will independently pass over any obstructions, and the depth of the whole gang may be regulated by operating lit'tinglever E. The tongues L' ot' beams A' are adapted, as shown, to support the plowbeams.

rlhe operation and advantages of my invention will be readily understood. rEhe drivewheels are propelled by a suitable. crank rod or shaft extending from an engine which is mounted on platform A between boxes Z Z.,

The drive-wheels thus carry the machine forward, dragging the plows after to open the soil. Itis simple,easilyoperated,and efficient.

I claim and desire to secure by Letters Patent- The combination ofthe platform A, having boxes Z Z, opening Q, and rack or bracket R, axle B in' bearings G C, carrying drive-wheels D D, provided with notched iianges E E, independent collar H at one end, operatingvcollar H' at the other, lever L, limiting-bracket N, spring O, and lever I), as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
